Here are some replacements that I use for handling references as the normal pop
and push wont work:
function array_ref_push(&$array,&$ref){
$array[] =& $ref;
}
function &array_ref_pop(&$array){
$r =& $array[count($array)-1];
array_pop($array);
return $r;
}
function array_ref_unshift(&$array,&$ref){
array_unshift($array,'');
$array[0] =& $ref;
}
function &array_ref_shift(&$array){
$r =& $array[0];
array_shift($array);
return $r;
}
